Organic light emitting display device and head mounted display system having the same

An organic light emitting display device comprising:

• a display panel including a plurality of infrared pixels disposed in an infrared emission region, the infrared pixels configured to emit infrared light, and a plurality of display pixels disposed in a display region, the display pixels configured to emit visible light;
• and
• a panel driver configured to provide driving signals to the infrared pixels and the display pixels,
• wherein the display pixels includes red color pixels configured to emit red color light, and
• wherein a first emission layer included in each of the infrared pixels includes substantially a same material as a second emission layer included in each of the red color pixels.

An organic light emitting display device comprising:

• a display panel including a plurality of infrared pixels disposed in an infrared emission region, the infrared pixels configured to emit infrared light, and a plurality of display pixels disposed in a display region, the display pixels configured to emit visible light;
• and
• a panel driver configured to provide driving signals to the infrared pixels and the display pixels such that the display pixels are driven by a simultaneous emission manner,
• wherein each frame period of the simultaneous emission manner includes a non-emission period during which the display pixels do not emit the visible light and an emission period during which the display pixels simultaneously emit the visible light, and
• wherein the infrared pixels emit the infrared light in at least a part of the non-emission period.
